Bing more amenities in the flat to make it more convenient to people ( more knifes, a kettle, more stuffs to cook...) who would stay a long time. Though I think it is quite enough if you stay a week or 2 holidays. Ensure all is well working before hosting. AC were leaking during our stay and Internet connection was cutting once or twice per day. I think your internet provider can be reviewed. Last point if you rent your flat do not expect people from the building to help your hosts for anything. If people wants a taxi they should use grab and for groceries delivery they can use villa market delivery service. Overall the flat and location is quite nice and Narumon is a nice person as well. We stayed almost 2 months there for our baby delivery and we appreciated that she provided a baby cot and bathtube ( though it was broken) for our baby. I would recommence to stay there.
